Black powder coating.
High-performance, stock-style bolt-on replacement for Twin Cam models, compatible with stock headers, rocker boxes, and exhausts.
The heads are 79 cc and have 1.940" diameter intake valves and 1.575" exhaust valves.
The head will handle up to .650" lift and is set up for use with up to .186" intake TDC lift and .179" exhaust TDC lift in combination with stock pistons.
This allows the use of S&S 510, 570 and 585 camshafts.
Heads can be covered up to 0.060" to increase compression, but then valve lift clearance checks are required.
Expected compression ratios for unmodified heads with stock pistons will be approximately 9.8 CR (96"), 10.2 CR (103"), 11.1 CR (103" with pop-up S&S pistons), and 10.8 CR (110").
Heads come complete with valves, guides and valve springs installed.
Note: Compatible with stock rocker covers, but S&S Compression Release Cams or S&S Easy Start must be used to retain Easy Electric Start due to the higher compression ratio.
The heads are machined to accept compression releases and manual compression release plugs are included.
Note: Not compatible with original rocker cover gaskets.
Must use special rocker cover gasket set 532583 with original rocker covers.
These are necessary for proper engine breathing.
Fits: > 06-17 Twin Cam (excl. Twin-Cooled models) (NU)
